How can you migrate your system from one partition to another?

I have two sections:
/dev/sda1 20G / it system
/dev/sda9 68G there I want to move the system to more locations
How can I do this?

I had the idea to do rsync and then in /etc/fstab to fix /dev/sda1 on /dev/sda9.
Which files/folders not to copy? For example, /proc/kcore I can't copy.

Use dd. Make an image root partition and put it on a larger partition, then make the resize FS.

Why not resignate and move the partitions using GParted?

@Eudora, using GParted. The second button on the tab - "resize/move" - Lorena.Connelly7 commented on March 19th 20 at 09:32

@Eudorait should be done from a boot disk LiveCD. Can Ubuntu can GParted LiveCD. - Lorena.Connelly7 commented on March 19th 20 at 09:38

exclude /dev /lost+found /proc /run
plus look at the output of the df command and eliminate all the extra mount.

as an option to boot from the live CD. it your root is used, the excess is not mounted. it is mounted and the partition where you want to copy. rinkausi the root amplitude.
also in the live-SD edit fstab, and after chrootишься the new root and "restore" gross out - he will register correctly boot from the new partition. (Googly - informations much).
